Starting at the trailhead in Garrett, you will ride a four mile section of the Great Allegheny Passage, ending in your dramatic trip across an antique train trestle, 2,000 feet long and 100 feet high. As you look down from the bridge, you will see farm fields, passing trains, and the Casselman River Valley below.

This flat, easy ride passes through old maple forests and open pastures with grazing dairy cattle. The Casselman River weaves in and out of view while the giant windmills of the Green Mountain Wind Farm appear and vanish just as suddenly.

From the far side of the bridge, looking westward, the biker is faced with 100 miles of continuous bike trail all the way to Pittsburgh, much of it through forests like the one to the right. With a river always by your side, and only a rare chance to encounter an automobile, this is some of the finest nature biking to be found in the world.
